BED-SPRING.

SPECIFICATION forming partlof Letters Patent No. 279,731, dated June 19,1883. 4

l Application filed pm 21, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN U. FIEsrER, a citizen of the United States, anda resident of Cambridge, in the county of Guernsey and State of Ohio,have invented certain new and useful Improvements in Bed-Springs; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itap- Io pertains to make and use the same, reference being had to theaccompanying drawings, and to letters or iigures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a side view.

Fig. 2 is a vertical section, and Fig. 3 is a horizontal sectional view.

This invention has relation to that class of bed-springs in which adouble spiral passes from the top of the spring-one internal and 2o theotherexternaludown to the slat to which it is fastened; and it consistsin the novel construction and arrangement hereinafter fully described,and particularly pointed out in the claim appended.

In this class of springs, heretofore, the double spirals pass down tothe slat, and each of them fastens with an angular hook, one fasteningbeing at each side of the slat; hence the spring occupies the middle ofthe slat. My object is 3Q to fasten both lower coils `with a single hookengaging one side of the slat, and to have the hooks engaging alternatesides of the slat, so that the springs will not be in line on the slats,but will be in zigzag form thereon. In the old 3 5 manner of forming thedouble-spiral spring two coils rest on the slat, and two hooks arerequired to fasten them to the slat, which entails a useless waste ofwire. In my construction the lower end of the outer coil passes throughabove the lower inner coil, as shown in 4o the drawings, and the hookwhich is formed on the lower end of the inner coil clamps both lowercoils to the slat. The extreme end of the clamp is provided with aish-hook-formed hook instead of the ordinary angle-hook,whichfacilitates the placing of the spring upon the slat. t

Referring by letter to the drawings, a designates the double spiralspring. b designates the outer coil, which terminates in the arm e. 5o ddesignates the inner coil, which is provided at its lower end with aspring-clamp, e, having at its termination the fish-hook end f, whichinsures a biting engagement with the under face of the slat. The arm cpasses over the lower coil, h, and under the upper horizontal portion ofthe spring-clamp, as shown, s0 that when the clamp is sprung to placeupon the slat both coils are secured by asingle hook.

The advantages of this construction in cheap- 6o ness and ease ofputting in place are obvious.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A double spiral bed spring having the lower end of the outer coil passedover the lower inner coil and the upper arm of the spring-clamp formedon the lower inner coil passed over the lower end of the outer coil, andprovided at its terminus with a sh-hook 7o bend, substantially asspecified.

In testimony whereof I afx my signature in vpresence of two witnesses.
